I sometimes forget that I even have these going. Hopeful to relocate them outdoors by months end.
Plan is to take clones around the 2 month marker and flowering them to sex and test, that of course if they're photos.
I've never grown an auto, but I would think if they're autos they'll be showing preflowers within weeks.
Easy enough... time tells all. Got 9 beaners of these left for a rainy day or gifts.
